THEODORE HARTUNG, OF CHICAGO, ILLINOIS, ASSIGNOB OF ONE-HALF TO ERNESTJ. NOLIN, OF SAME PLACE.

INVOICE OR SCRAP BOOK.

SPECIFICATION forming part of Letters Patent No. 238,233, dated March 1,1881.

Application filed December 4, 1880.

To all whom it may concern Be it known that I, THEODORE HARTUNG, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Invoice or Scrap Books, of whichthe following, in connection with the accompanying drawings, is aspecification.

In the drawings, Figure lis an end or edge view of a closed bookembodying my invention; Fig. 2, a horizontal cross-section of the openbook; Fig.3, a like representation of the back-piece detached and Fig.4, a perspective of the same.

Like letters of reference indicate like parts.

In the drawings, A represents the cover of the book.

B is the back-piece. The back-piece consists of the under piece, C, madeofcanvas or other suitable flexible material, ofthe ribs D D, made ofstraw-board, paper, pasteboard, wood, or other suitable materialarranged at suitable distances apartlongitudinally along the piece C,and ofthe top piece, E, made of cloth, leather, or other suitablematerial applied adhesively to piece C and to the ribs D D, allsubstantially as indicated in the drawings.

F F are the leaves, which are arranged together in separate sections aa, each independent of the other. The leaves in each section should beconnected to each other along the line of folding by means of stitching,which may be done either with thread or wire, or they may be connectedin any other wellknown or suitable way. The sections a, a, I

5 place between the ribs D D, and each channel or groove between theribs contains a section, as shown. The sections may be secured in theirplaces between the ribs either by means of glue or by sewing, or in anyother suitable way.

A flexible back-piece capable of being applied with facility to thecover A is thus produced, and the sections a a may be readily (Nomodel.)

applied to the back-piece, and each section will be positively separatedfrom the other v the cover.

It will be perceived from the foregoing description, and by reference tothe drawings, that the ribs D D being separated, as shown, 5 do notinterfere with the proper flexibility of the back-piece B, but tend torender it firm, strong, and durable. It will also be perceived that theribs 1) D take the place of the stubs which usually form a part of theleaves of the sections, and are employed to keep the sections apartalong theirline of connection with the back-piece. By this means I avoidthe necessity of constructing such stubs and keep the sectionspositively and firmly separated at their bases. This is the essentialfeature of my invention. Besides, the book may be spread open moreflatly than books of this class can ordinarily be without injury. Theconstruction of the book is also greatly facili- 7o tated.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is-

The combination, in an invoice or scrap book, of the cover A, theflexible back-piece B, consisting of the under piece, C, and. top piece,E, the ribs D 1), arranged at intervals apart between the pieces B andE, and the sections a a, arranged between the ribs D D, substantially asand for the purposes specified.

THEODORE HARTUNG.
